i'm not sure that ND has more talent. maybe they have more experienced talent but Duke is no slouch. their sophomore class was rated #1 by HG i think coming out of HS and they have at least 2-3 kids in that class who are really good. i think Duke has a big advantage in the post with Williams, Henson, and Vernery. but ND has shown that it's tough to stop their guards and wings and i think Diggins and Novasel are better than Duke's backcourt.
Duke's problems recently, IMHO, have been an inability to score and then against a good team like UCONN, they slow down on defense and get shellacked. but like you i have no idea what to predict. it will be a great test for both teams and a great chance for Duke to show they are ready to play with the big boys.
